Privacy: we log time, tool, argument names and lengths, and a daily keyed hash of your IP, never argument values or your raw IP, and delete records after 30 days. Records from before 26 September 2026 used a fuller format and are deleted by 26 October 2026. Details: https://x402.nsgoods.org/privacy

Which x402 endpoints actually take a payment, what they cost, and which hosts have gone dark. Ask from Claude, Cursor or any Streamable HTTP client.
